New volcano appears, wasn't there days ago

East of the Indonesian island Java, in the sea between Java and Bali, a new island has risen from nothing within a few days. It is probably of volcanic origin. The location is not so very far from Tambora.
 So west of Java the Anak Krakatoa is active, in the middle of Java the Merapi is very active and east of Java a new island has appeared in the sea, which wasn't there a few days ago. Fears of a coming mega-eruption is real.
